OLFA RATCHET-LOCK UTILITY KNIFE

This knife is larger than other Olfa standard duty cutters, providing more leverage for tougher cutting projects. It features a positive slide lock, a ratchet wheel blade locking mechanism to hold blade in place and a stainless steel blade channel that holds a blade tight. The snap-off blade is long-lasting and durable, and provides a new sharp edge with each snap. Uses OLAB and OLA1160B blades.
